SERVICE POINTS OF DISASSEMBLY
7.
REMOVAL OF FRONT BRACKET/lG. REAR BRACKET
(1) Insert plain screwdriver between front bracket and stator
core and pry downward.
Caution
Do not insert screwdriver too deep, as there is danger
of damage to stator coil.
(2) Rear cover may be hard to remove because a ring is used
to lock outer race of rear bearing. To facilitate removal of
rear cover, heat just bearing box section with a 200-W
soledering iron.
Do not use a heat gun, as it can damage diode assembly.
1. REMOVAL OF PULLEY
Clamp the rotor in a vise with soft jaws.
11. REMOVAL OF REGULATOR AND BRUSH HOLDER
(1) Unsolder three stator leads soldered to main diodes on
rectifier.
(2) Unsolder two plates soldered to rectifier.
Caution
1. When soldering or unsoldering, use care to make
sure that heat of soldering iron is not transmitted
to diodes for a long period. Finish soldering or un-
soldeing in as short a time as possible.
2. Use care that no undue force is exerted to leads of
diodes.
INSPECTION
ROTOR
l
Check rotor coil for continuity. Check to ensure that there is
continuity between slip rings.
If resistance is extremely small, it means that there is a short.
If there is no continuity or if there is short circuit, replace rotor
assembly.
